President Roosevelt had a personal telegrapher

In an era before instantaneous global communication, the telegraph allowed
President Franklin Roosevelt to receive vital information and conduct critical
government business while away from the White House.
This portable telegraph and vibroplex key
were used by Dr. E. Stuart Davis, communications aide and personnal
telegrapher during President Roosevelt’s travels. 1

The portable telegraph and Vibroplex key used by Dr. Davis are part of a display of
presidential memorabilia in
The Hall of Presidents
at Walt Disney World.
